:D:lol2::lol2::D:wub:2006 vulcan, 168k miles, cel came on , codes read p0171 / p0174. both banks lean
thanks to previous posts about this codes i looked for a leaky vqacuum line or the notorious right angle boot at the pcv.
it seems that the 06 has a very diffrent pcv ($85!!!)and has no boot over it to crack and leak.
some one had also posted info about the MAF being dirty.
got some maf cleaner, got a t20 torxs, pulled maf out, sprayed it good (cost $8) reinstalled it, no cel, drove for 100 miles, still good.
thanks to all of the members that did the trouble shooting and posting their findings.
